i think taking a break late last year is when the marketplace changes took place was good and bad lol, haven't had too many dramas until we condensed the magic boxes in an orderly fashion just recently, to be honest the transition wasn't so bad and things kept going fairly smoothly apart from the odd undelivered item.
it was just a bit of a shock to realise the free test delivery had gone during the migration, in hindsight we would've just left it all alone for now but it was part of a big shop/product update which required more space and moving of the magic boxes.
it seemed to go wrong when removing items from multiple magic-boxes and condensing them in to a single box for each category, only 10 or so items per box where previously it was one box per item.. always thought it was one item per box .. lol?
anyway, on top of that we copied them to inventory and re-rezzed them 300m up in the skybox, then deleting the old ones, re-inserting new scripts from a new magic-box ( same current version as the old but did it to be sure ) aswell as then resetting them, and syncing them with marketplace, got nice pretty swirls and all seemed ok until we started testing by purchasing our own product, the first couple worked, then seemingly random items didn't work, infact most didn't..
by then we were a little frustrated at the lack of test delivery and decided to leave it all go for now ( we sell the same price as in world, and don't ever charge for demos ) .. so yea the marketplace commission thing put us off for now.
thanks for the attentive reply though Parrish, we'll maybe test a few demos and try methodically getting those relisted again once other priorities are out of the way, and will definitely take note of the grid status and other concurrent issues whilst testing in case something seems apparent.
thanks again
